充电完成后设备/充电器是否会消耗电源？ -- charging 领域 android 相关的问题

Does the device/charger consume power after charging is complete?

简体版||繁體版

问题

中文

我对效率有点强迫，我注意到我的两个Android设备中的至少一个告诉我在充电完成后拔掉它以节省能源。我的问题是：

这是否根据硬件和/或软件而变化（可能是我的LG Optimus T电话在收费后继续消耗类似的电源，但我的Nexus 7没有）？
如果设备在收费之后的设备继续"消耗" 电源，它会在哪里（热力学定律和全部）？

在寻找我的答案时，我发现了以下问题，但不适用于我的问题：

不断充电伤害我的Android手机？ < / li>
Ac-USB充电设备发出声音设备完全充电
我的手机充电器的哪些组件产生了唧唧声，它是如何做到的？

english

I'm a bit OCD about efficiency and I have noticed that at least one of my two Android devices tells me to unplug it after charging is complete to save energy. My questions are:

Is it true that a chargeable USB device may or will continue to consume similar amounts of power if it remains plugged in after fully charging?
Does this vary based on hardware and/or software (Is it possible my LG Optimus T phone continues to consume similar power after it is charged, but my Nexus 7 doesn't)?
If a device continues to "consume" power after it is charged, where does it go (laws of thermodynamics and all)?

In searching for my answer, I have found the following questions relevant but not entirely applicable to my question:

Does constant charging harm my Android cellphone?
AC-USB Charging Device Makes Sounds when Device Fully Charged
What component of my phone charger produces chirps and how does it do that?

需要考虑一些有趣的点，比Android在自然中取向更多的电子产品。 Simon 2013-02-28 14:59:12Z, License: CC BY-SA 3.0

@simon是的，很难为这个问题选择最合适的论坛，但由于它部分特有于我的Android设备特有的警告消息，我认为这是合适的。而且我确定（看到这个问题的评级）许多Android用户都有类似的问题。 BlueMonkMN 2013-03-06 19:25:00Z, License: CC BY-SA 3.0

@Simon yes, it was hard to pick the most suitable forum for this question, but since it was partly specific to a warning message specific to my android device, I decided here would be appropriate. And I'm sure (seeing the rating on this question) many Android users have a similar question BlueMonkMN 2013-03-06 19:25:00Z, License: CC BY-SA 3.0

最佳答案

就像任何其他设备一样，无论电池是否满是或需要充电，都会消耗能量。当您的设备完全充电并静止插入时，充电器补充了手机使用的能量。它使用较少的能量而不是充电而是仍然存在。这被称为涓流充电它建议拔掉设备，因为保持电池随时完全充电，将减少其容量并使电池芯片更快。电池需要部分放电，然后全面地充满了充满电，以便延长其生命。

以下句子来自关于延长电池寿命的文章

让 - 看看现实生活中的情况，并检查锂离子电池的强调遇到的内容。大多数包装最近三到五年。环境条件，而不是单独骑行，是寿命的关键因素，<强劲>，最坏情况是在高温下保持完全充电的电池。在电网上运行膝上型电脑时，这是这种情况。在这些条件下，无论是否循环，电池通常会持续约两年。包装不会突然死亡，但会带来较低的次数。

您还可以在此处读取部分放电和充电：

TechRepublic - 延伸锂的五个提示电池寿命

Like any other device, regardless if the battery is full or need charging it consumes energy all the time. When your device is fully charged and still plugged in then the charger replenishes the energy used by the phone. It uses less energy than when charging but still. This is called Trickle charging It is advised to unplug device because keeping you battery fully charged all the time will reduce its capacity and make your battery die faster. Battery needs to be partially discharged and then be fully charged on a semi-regular basis in order to prolong its life.

The following sentence is from Article on prolonging battery life

Letxe2x80x99s look at real-life situations and examine what stresses lithium-ion batteries encounter. Most packs last three to five years. Environmental conditions, and not cycling alone, are a key ingredient to longevity, and the worst situation is keeping a fully charged battery at elevated temperatures. This is the case when running a laptop off the power grid. Under these conditions, a battery will typically last for about two years, whether cycled or not. The pack does not die suddenly but will give lower runtimes with aging.

阅读链接文章的头条新闻，我没有看到任何关于让电池充满电的糟糕。实际上（对于锂离子电池）似乎是优选的 BlueMonkMN 2013-02-28 18:48:46Z, License: CC BY-SA 3.0

锂离子电池不应低于安全电压率，因为它可能会损坏细胞。如果您阅读完整的文章，您将看到：“连续涓流充电会导致金属锂的电镀，这可能会损害安全性。为了最大限度地减少应力，请将锂离子电池保持在4.20V /电池峰值电压下。尽可能的时间。“更多关于寄生载荷和电池的应力更多。 NatWeb Solutions 2013-02-28 20:58:27Z, License: CC BY-SA 3.0

在使用时，唯一的是你电池的东西是手机本身。这里已经讨论了持续的充电和延长电池寿命： NatWeb Solutions 2013-03-01 12:04:21Z, License: CC BY-SA 3.0

嗨，我已经在家里测试过。正常充电4.5瓦的能量排水从插座上，然后充满电我的仪表显示0持续2-4分钟，然后它开始充电，从插座上需要2.9瓦。充电持续2-3分钟，然后再次停止等待电池稍微下降。根据您的手机条件（屏幕上打开，呼叫等），收费过程更频繁，但每次它使用的能量略低于正常充电。 NatWeb Solutions 2013-03-11 09:39:34Z, License: CC BY-SA 3.0

Reading the headlines of the linked article I don't see anything about it being bad to keep the battery fully charged. In fact (for Lithium ion batteries) it seems to be preferred BlueMonkMN 2013-02-28 18:48:46Z, License: CC BY-SA 3.0

Lithium ion batteries should not be discharged below the safe voltage rate because it may damage the cell. If you read the full article you will see that: "A continuous trickle charge would cause plating of metallic lithium, and this could compromise safety. To minimize stress, keep the lithium-ion battery at the 4.20V/cell peak voltage as short a time as possible." And lots more about parasitic load and stress for the battery NatWeb Solutions 2013-02-28 20:58:27Z, License: CC BY-SA 3.0

The only thing which drains you battery is the phone itself while it's being used. Again constant charging and prolonging battery life have been already discussed here: NatWeb Solutions 2013-03-01 12:04:21Z, License: CC BY-SA 3.0

Hi, I have tested that for you at home. Normal charging 4,5 Watts of energy drain from the socket, then when fully charged my meter shows 0 for 2-4 minutes, then it starts charging and it takes 2.9 Watt from the socket. Charging lasts for 2-3 minutes and then it stops again to wait until the battery goes down a bit. Depending on condition of you phone (screen turned on, on call etc.) the charing process is more frequent but every time it uses slightly less energy then normal charging NatWeb Solutions 2013-03-11 09:39:34Z, License: CC BY-SA 3.0
